In the field of industrial respiratory protection, gas masks are the core equipment for dealing with toxic and harmful gas scenarios such as organic vapors, acidic gases, ammonia, and carbon monoxide. As a national brand in the domestic respiratory protection field, Fangdun has built a complete product matrix around the dual needs of "dust prevention+gas prevention", including the combination of 5000 series filter boxes and 1680 full face covers, covering multi-layer protection needs from conventional chemical to heavy dust and toxic composite environments.
5000 series toxin filter box: Choose to use for different harmful gases
The 5000 series adopts a dual filter box design and a trapezoidal groove structure to shift the center of gravity backwards, avoiding neck fatigue during long-term operation; The outer shell of the filter box is made of high-strength ABS material, and the interior is filled with coconut shell activated carbon blocks treated with special processes - compared to traditional cylindrical carbon, the pores are more developed, the specific surface area is larger, the adsorption rate is faster, and the aging time is longer. The grid structure has many gaps, and when combined with special chemical immersion treatment, it can provide directional protection for different gases;
The filter box is connected to the face mask through a unified three-stage interface and can be combined with a 5101N filter cotton cover or 5101N filter cotton to achieve "dust and toxin prevention".
FJ-35 receiver seat, equipped with a set of face masks that simultaneously block dust and toxic gases
In response to the complex environment of dust and toxic gases, Fangdun has designed the FJ-35 filter box receiver. The three-point buckle structure can be installed on top of the 5000 series filter box, and the upper layer is equipped with 2101N/2202N/2901P/2907P filter cotton or 6101P/6102P filter box, which can protect against dust and harmful gases without changing the face mask. It can be used in chemical, automotive repair, smelting, and disinfection workshops. The main body of the bearing seat is made of PP material, which is impact resistant, acid and alkali resistant, and is not easily deformed after long-term use.
1680 full face mask: more secure in high concentration toxic gas environment
When the concentration of toxic and harmful gases in the work environment is higher or longer wearing time is required, the 1680 full face mask is a more reliable choice. The large window adopts a high-performance polycarbonate screen, with 180 ° visual distortion free, anti fog and scratch resistant; Five point fixed headband+high elasticity soft silicone that fits the Asian face shape; The exhalation valve quickly eliminates dampness and heat, and the three-point snap on interface is compatible with both the filter box and the dust filter box. Paired with the 5000 series filter box, it forms a heavy-duty antivirus solution of "full face mask+dual filter box".
Fangdun， From the gas classification of the filter box, to the dust and toxin expansion of the receiving seat, to the airtight upgrade of the full face mask, the gas mask has been made into a modular system that can be assembled according to the scene - this is also a microcosm of domestic respiratory protection brands breaking free from overseas pricing power and providing Chinese workers with cost-effective solutions.
